True or False: Plan B won’t work if you’re already preggers.
Answer: That’s true
First things first: Plan B *isn’t* an abortion pill—it’s a backup option to help prevent a pregnancy before it starts when used after unprotected sex or birth control failure. So, no: it doesn’t work if you’re already pregnant. Here’s why: Plan B works by temporarily delaying ovulation—so essentially, that means that if there’s no egg, there can be no fertilization, and thus, there can be no pregnancy.
Basically, you just take Plan B as directed—it’s most effective the sooner you take it (within 72 hours after unprotected sex)—and then you can (and should) start up your regular birth control regime, stat. And remember: There aren’t any long-term effects from taking Plan B (and nope, it won’t negatively impact your ability to get pregnant in the future either).
